  2. 1. Host-Pathogen Responses during Giardia infections

    Author : Emma Ringqvist; Staffan Svärd; Patricia Johnson; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Giardia; parasite infection; host-parasite releationship; immune activation; virulence factor; immune evasion; Cell and molecular biology; Cell- och molekylärbiologi; Microbiology; Mikrobiologi; mikrobiologi; Microbiology;

    Abstract : Giardia lamblia is a eukaryotic parasite of the upper small intestine of humans and animals. The infecting trophozoite cells do not invade the epithelium lining of the intestine, but attach to the brush border surface in the intestinal lumen. The giardiasis disease in humans is highly variable. READ MORE

  4. 2. Structure, function and metabolic stability of antisense RNAs

    Author : Fredrik Söderbom; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Microbiology; Mikrobiologi; Microbiology; Mikrobiologi; mikrobiologi; Microbiology;

    Abstract : Antisense RNAs usually are small, highly structured, unstable RNAs that control a varietyof different biological processes. They exert their effect by binding to complementarytarget RNAs and thereby inhibit their functions. READ MORE

  5. 3. The type I-E CRISPR-Cas system : Biology and applications of an adaptive immune system in bacteria

    Author : Lina Amlinger; Magnus Lundgren; Peter Fineran; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; CRISPR; CRISPR-Cas; virus defense; bacteria; bacteriophage; adaptation; spacer integration; interference; gene silencing; fluorescent reporter; Escherichia coli; Mikrobiologi; Microbiology;

    Abstract : CRISPR-Cas systems are adaptive immune systems in bacteria and archaea, consisting of a clustered regularly interspaced short palindromic repeats (CRISPR) array and CRISPR associated (Cas) proteins. In this work, the type I-E CRISPR-Cas system of Escherichia coli was studied.CRISPR-Cas immunity is divided into three stages. READ MORE

  6. 4. EF-Tu and RNase E : Essential and Functionally Connected Proteins

    Author : Disa L. Hammarlöf; Diarmaid Hughes; Måns Ehrenberg; Gerhart Wagner; Richard H Buckingham; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; bacterial growth; translation; EF-Tu; RNase E; mRNA; RNA degradation; Molekylär cellbiologi; Molecular Cellbiology; Mikrobiologi; Microbiology;

    Abstract : The rate and accuracy of protein production is the main determinant of bacterial growth. Elongation Factor Tu (EF-Tu) provides the ribosome with aminoacylated tRNAs, and is central for its activity. In Salmonella enterica serovar Typhimurium, EF-Tu is encoded by the genes tufA and tufB.

  7. 5. Control of Chromosome and Plasmid Replication in Escherichia coli

    Author : Jan Olsson; Kurt Nordström; Santanu Dasgupta; Måns Ehrenberg; Anders Lobner-Olesen; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Microbiology; Mikrobiologi; Microbiology; Mikrobiologi; mikrobiologi; Microbiology;

    Abstract : Life is cellular. Cells grow and divide to give two new cells; this process is called the cell cycle. The chromosome in a bacterium is replicated into two identical copies before the cell divides. DNA replication is a fundamental process common to all forms of life. READ MORE
